I am an inexperienced photographer. I would like to purchase a new digital camera. I have decided that I can narrow down the choices to these six options. If you guys have any opinions on these, negative or positive, please give me the feedback!

Canon powershot A620
Sony Cybershot DSC-T30
Kodak Easyshare z612
Panasonic Lumix DMC-LZ5k
Casio Exilim EX-Z10
Fujifilm fmcpix F30

I know that these are different sizes, and as far as sizes go... the Sony is pretty nice, however I worried about its ability to do low light shooting, and the big screen on the back breaking. Any suggestions or advice?
